Abstract

A camera having a zooming lens barrel. The zooming lens barrel includes: plural lens component; a guide portion for guiding one of the plural lens components along the guide portion in an optical axis direction of the plural lens components in which the guide portion has plural focal distance positions; a driver for moving one of the plural lens components along the guide portion in the optical axis direction; a movement controller for controlling the driver so as to move one of the plural lens components to a predetermined position. The guide portion includes a first area for performing focusing from the first focal distance position, a second area which is not used for focusing, and a third area for performing focusing from the second focal distance position.
